The KDE start command appears to have been renamed from startkde to startplasma-x11. This breaks sawfish-kde5.desktop and its session script. In Debian the change occurred between plasma-workspace versions 4:5.14.5.1-1 and 4:5.17.5-4. ln -s startplasma-x11 startkde seems to fix it, but is perhaps not the ideal long run solution.
